Solving Common Issues with the CRG9 Monitor on Arch Linux
The Samsung CRG9 is a popular monitor for productivity and gaming, but some users may encounter issues when using it with Arch Linux, Xorg, and EXWM/Compton or Picom compositor. This article covers three common issues: stuttering, tearing, and lag, and provides detailed solutions to help you get the most out of your new monitor.
Issue 1: Stuttering
Stuttering, or micro-stuttering, is a common issue that can occur when using a high-resolution monitor like the CRG9. This can be caused by a number of factors, including outdated drivers, insufficient GPU power, or misconfigured settings.
Solution:
To solve stuttering issues on the CRG9 monitor, follow these steps:
- Make sure you have the latest drivers for your AMD Radeon 6500 XT graphics card installed. You can check for updates in the Arch Linux package manager.
- Check that your GPU is powerful enough to handle the high resolution of the CRG9 monitor. If necessary, consider upgrading to a more powerful GPU.
- Try adjusting the EXWM/Compton or Picom compositor settings. You can try changing the refresh rate, enabling VSync, or adjusting the compositor's performance settings.
# Example EXWM/Compton compositor settings for the CRG9 monitor
(setq exwm-compton-options
'(
; Enable VSync
(-vsync)
; Set refresh rate to 120Hz
(-refresh 120)
; Adjust performance settings
(-opacity 0.95)
(-shadow 0)
(-blur-background 0)
(-blur-strength 0)
))
Issue 2: Tearing
Tearing is a visual artifact that can occur when the monitor's refresh rate is not synchronized with the GPU's frame rate. This can result in a visible line down the middle of the screen, which can be distracting and unpleasant.
Solution:
To solve tearing issues on the CRG9 monitor, follow these steps:
- Make sure you have the latest drivers for your AMD Radeon 6500 XT graphics card installed. You can check for updates in the Arch Linux package manager.
- Enable VSync in your EXWM/Compton or Picom compositor settings. This will synchronize the monitor's refresh rate with the GPU's frame rate, preventing tearing.
- Try adjusting the refresh rate of the monitor. The CRG9 supports a refresh rate of up to 120Hz, which can help reduce tearing.
# Example EXWM/Compton compositor settings for the CRG9 monitor with VSync enabled
(setq exwm-compton-options
'(
; Enable VSync
(+vsync)
; Set refresh rate to 120Hz
(-refresh 120)
; Adjust performance settings
(-opacity 0.95)
(-shadow 0)
(-blur-background 0)
(-blur-strength 0)
))
Issue 3: Lag
Lag, or input lag, is the delay between when you press a button or move the mouse and when the action is displayed on the screen. This can be a common issue with high-resolution monitors like the CRG9, especially when using a compositor.
Solution:
To solve lag issues on the CRG9 monitor, follow these steps:
- Try disabling the compositor or adjusting its performance settings. This can help reduce input lag and improve responsiveness.
- Check that your GPU is powerful enough to handle the high resolution of the CRG9 monitor. If necessary, consider upgrading to a more powerful GPU.
- Try adjusting the refresh rate of the monitor. The CRG9 supports a refresh rate of up to 120Hz, which can help reduce lag.
In this article, we covered three common issues that can occur when using the CRG9 monitor with Arch Linux, Xorg, and EXWM/Compton or Picom compositor: stuttering, tearing, and lag. By following the solutions provided, you should be able to resolve these issues and get the most out of your new monitor.
